Key Takeaways
- • BITO, the ProShares Bitcoin ETF, trailed the spot-holding iShares Bitcoin Trust ETF (IBIT) across every measured window, according to 24/7 Wall St., which attributes the gap to BITO's futures structure.
- • Futures roll costs compound over time as expiring contracts are swapped for new ones, eroding exposure in a way direct-holding funds like IBIT do not experience.
- • Over the year to October 7, 2026, BITO fell 35.76% and IBIT fell 33.79%, against a 29.64% decline in Bitcoin itself.
- • The article cites investor flows of $69 billion into IBIT versus $1.69 billion remaining in BITO as evidence that investors have shifted toward direct-holding products.
- • BITO launched on October 19, 2021 as the first U.S. Bitcoin fund, but the article argues its futures-based design is now ineffective relative to spot alternatives.
Summary
The ProShares Bitcoin ETF (NYSEARCA: BITO) became the first U.S. Bitcoin fund when it launched on October 19, 2021, offering exposure to Bitcoin (CRYPTO: BTC) through futures contracts rather than the coin itself. According to 24/7 Wall St., BITO's structure has left it trailing the iShares Bitcoin Trust ETF (NASDAQ: IBIT), which holds Bitcoin directly, across every measured window. The publication attributes the shortfall to the recurring cost of rolling futures contracts forward, which compounds over time and shrinks exposure with each contract swap. The article notes that this drag is absent in direct-holding structures such as IBIT.
Over the past year, the two funds fell in close step with the underlying asset. BITO posted a price change of -35.76% and IBIT posted -33.79%, while Bitcoin declined 29.64% between October 7, 2025 and October 7, 2026. The article stresses that the comparison is about structure rather than the merits of holding Bitcoin, and that whether to own the asset at all is a separate decision.
The publication cites investor flows as evidence of a shift in preference, reporting $69 billion flowing into IBIT versus $1.69 billion remaining in BITO. It also states that Bitcoin gained 58% over five years, a figure the article uses to frame the long-run comparison. The article's matching-window analysis, which compares both funds over identical dates, supports its conclusion that the spot fund has outperformed the futures fund in each measured period.
